AN'IPROOF Application filed June 7,

My invention relates to improvements in cupboards to keep away ants and the objects of my improvement are to provide a cupboard with circular shelves, a frame to support the shelves, bearings at the top and bottom of the cupboard permitting the rotation of the frame with its shelves, and cups surrounding the bearings. In the cups is placed either a liquid, a powder, or other insecticide which will shut off all approach to the cupboard.

These objects are accomplished by the means illustrated in the accompanying drawings in which Figure I is a sectional elevation of the cupboard and rotary shelves,

Fig. II is a plan view of the top bearing,

Fig. III is a plan view of the to cup,

Fig. IV is a front elevation 0 one of the frame straps,

Fig. V is a plan view of the bottom cup,

Fig. VI is a plan view of either top or bottom bearing piece, and

Fig. VII is a top view of one of the circular shelves.

The walls of the cupboard 1 may be of wood or metal as preferred. Fastened to the floor of the cupboard is a combined cup and bearing 2. Revolving upon this bearing is the journal of frame piece 3, cast in the shape of a cross. T 0 each arm of this cross is attached a metal strap 4 which is bent vertically at right angles and rises and attaches to a similar cross shaped frame piece 5 above. Between the iron straps 4 and bolted to them are the cupboard shelves 6.

Above the journal of the upper crossshaped frame piece 5. and fastened to the ceiling of the cupboard is the bearing 7. The upper cup 8 may be made greater in diameter than the cupboard shelves 6 so as to make it CUPBOARD.

impossible for insects to drop upon the shelves from the ceiling. In the center of the cup 8 is a collar 9 surrounding the spindles both of the stationary bearing 7 and the rotary bearing 5, and serving to hold the latter in place.

The four arms of the two cross shaped frame pieces are provided with slots 10 so that the iron straps may be drawn in and bolted close to the center of the hearings, or pulled out and bolted near the ends of the arms of the crosses; in this way circular shelves of different diameter may be used to fit cupboards of different sizes.

The vertical straps are provided with short slots 11 to permit of adjustment in leveling the shelves when they are bolted to the straps. The bottom cup is provided with lateral projections 12 by which it is bolted to the floor of the cupboard. The metal shelves 6, have perforations 17 to assist ventilation.

I claim:

1. A cupboard having a plurality of horizontal shelves, metal standards supporting said shelves, and top and base members affixed to said standards having slots to permit of the lateral adjustment of said standards for the accommodation of sets of shelves of different dimensions.

2. An ant-proof cupboard having in combination top and bottom members, pins on said top and bottom members upon which the cupboard may rotate, standards connecting said top and bottom members, radial slots in said top and bottom members permitting lateral adjustment of said standards, a plurality of horizontal shelves supported by said standards, and liquid cups surroimding said pins as a safeguard against insects.

In testimony whereof, I hereby aliix my signature.
